The murder of Pauline Devor

As indicated by murderpedia.org, Delores and Monica orchestrated the murder following the filing of a case of financial fraud by Pauline Devor against her daughter. Delores had been using the credit cards belonging to Pauline without authorization, and when Pauline pressed charges, Delores orchestrated the revenge.

Bob Devor was aware of the tension but was nowhere around the scene of the crime. Delores and Monica used drugs on the evening of the killing before they implemented their scheme. They got Pauline Devor out of her house and then attacked her physically.

Delores went inside the house and grabbed a gun, which she used to shoot Pauline Devor. They incinerated the body using gasoline and threw away the rest of the evidence in a nearby river to conceal the crime.

Investigation and arrests

The case went cold for almost two years. Throughout this time, Bob and Delores maintained their relationship. As Northwest Arkansas Democrat-Gazette reports, Delores went back to Pauline's residence and claimed her property, including her car and rent payments.

Nevertheless, investigators became suspicious as a result of inconsistencies in Bob's account and the absence of forced entry at the crime scene. A breakthrough came when Monica, arrested for a separate fraud case, confessed to the crime in exchange for immunity. She provided details about the murder, which led police to search the crime scene again.

According to murderpedia.org, they discovered human bone and teeth fragments were discovered, confirming Pauline Devor’s death. Delores was arrested soon after Monica's confession. She tried to commit suicide but was discovered in time and hospitalized. She was charged with capital murder upon recovery.

Bob was not charged initially due to insufficient evidence, but subsequent investigations implicated him in the cover-up.

Sentencing and aftermath

Delores eventually admitted to the crime, disclosing her affair with Bob and his awareness of the murder. Northwest Arkansas Democrat-Gazette reports that she was sentenced to 30 years in prison for her involvement in the murder. Bob was found guilty of tampering with evidence and sentenced to 10 years in prison and a fine of $15,000.
